Collection: Coupling Parts & Accessories

Find trailer coupling parts and accessories for repairs and maintenance, including AL-KO dampers, rubber bellows, master cylinders, handbrake components and stabiliser friction pads. The range also includes towballs, adaptor plates, breakaway cables and replacement coupling hardware.

Match replacement parts to your coupling’s model and part number before ordering. Check dimensions, master-cylinder bore size and stabiliser compatibility where relevant, as similar-looking components can suit different coupling assemblies.
